a The casing of the battery is made of sheet metal, in box form, generally rectan ular in cross section, providing the rear wa l 2 and I sides 3, 3, inclosing the batter partition 5 extends lateral y across the ont of said chamber, engagingoif-set portions 6, 6, in the side walls, which extend by the front plate 8, thus providingand 1ncllo'sing the lamp chamber 9.

- The entire case is provided with a bottom 110 of any suitable material and a removable ciover 11. Said cover is preferably at an angle or slope across the top of the case, from the back portion downwardly toward the front, whereby to-ea'sily deflect any falling substance as -'coal 'or the like from the case. vThe cover 11 is designed to be removably secured upon the case for access to the interior, locked thereon against unauthorized recured centrall as by a rivet 16, the spring with downwardly turned terminal lips 18 of the bail terminals. The arms 17 are 'rewith ,the grooves, and'each is provi block 19 of magnetic metal. v The terminals 13 extend inwardly registering openings in side flanges 11 of the top 11 tionof-the' together, and the inner terminals 13 being tapered or rounded, easily slip inwardly past the terminals 18 of the spring arms 17 and become locked thereby. They are'released by the use of a special magnet in the possession of the foreman or mine boss only, and the device is thus proof against being openedby any one else.

The back 2 of the case is provided with supporting securing hooks 21, 22, respec tively formed'on the ends of a strap 23 which is 'ri'v'eted or otherwise secured to the back of the case and forwardly thereof, as at 7, 7 and are joinedmoyal. For such urpose I provide a cararm 17 exten ing in each direction toward the innerside of the cover and provided sil'ient for downward engaging pres'sclllrg, e

across its upper end portion with a bar or and also in the upper central porsides 3, positively securing them whichhas between the l speciflcation'oi Letters iatent. I Patented 18 mutation filed March 19, 1912. semrito. 684,870.

of j ars or vibrations. The lamp and battery and the inclosing case provided with these attaching hooks are shown in Figs. 1,2 and 3 as mounted u on my improved bracket which is especial designed for mounting u on the rear wal of the mine car orthe The bracket consists of a pair of li e. hooked bars 24 having downwardly turned back portions '25 terminating in inwardly directed pointed extremities 26.,

Extending inwardly and upwardly from the lower ends of the bars 24 are spring arms 27 having similar biting terminals 28,

, the other ends of the arms 27 being turned up in rounded form, as at '29, ada ted to bear with cushioning resistance against the face of the end wall 30 of the mine car. Across the upper and lower portions of bars 24 and rigidly connecting and holding them in position, are supportlng bars 31,32, re-

25 spectively, adapted to receive the supporting hooks 21 and 22. For the purpose of retainmg the device as thus mounted positively in position against dislodgment, I provide a sprmg tongue 33 secured at one end to one of the bars 24, as at34,'the other end being free. By this means the tongue 33 can be drawn outwardly at one'end and the hook 21 inserted behind it above bar 31, hook 22 at the same time being placed for engagement with bar 32, whereupon the lamp casing may be lowered to the position illustrated in Figs. land 2,'and spring tongue 33 will ositively hold the upper hook 21 against dislodgment or accidental removal. As thus mounted the is fixedly maintained in suitable operative relation to the end of the mine car and is capable of very considerable resilient movement toward and from it due to the elongated spring-like terminals of hooks 21 and 22.

, Within the cavity 4 of the casing is the battery. In the construction shown it comprises two outermost negative plates a and an intervening positive plate I), mounted so within the outersurroundmg insulating casmg 0, and separated by separatorsor spacers d of chem cally treated wood or other suitable materlal forming an electric ga Each n orm, of

tion' as that shown in m rior a lication Serial No. 651,424. i

The plates are inserted interior abutments 1 and g, suitably arranged across the'innerfaces of the walls and bottom of the case to. fixedly hold the plates in assembled position, with ample surrounding clearance space for the electro,

a statedflwi'thinthe'case c of hard rubber having a sealing 60 top e and mwardly and upwardly projecting fluid. Screwed into the upper portion of the cover 0 is a cap h having an enlarged head and a central perforating a erture 2' extending longitudinally throug out its length. The filler cap is somewhat concaved at its outer head portion and extends downwardl into the interior of the case to a point slightly above the normal level'of the electrolyte, as clearly shown in Fig. 5. It is provided with a transverse port j extending from one side to the other and communicat- I ing with the central port The object of of gases from within the, battery cavity through the lateral port 1' at either side and the central port 2' to the exterior, in whatever position the battery may assume. The extension of the plug it downwardly into the electrolyte cavity also prevents any leakage, irrespective of whatever angle or position the battery ma have.

' Conductors k, extend upwardly from this construction is to provide for ventilation the negative plates a, a, through the cover a of the case and are joined by a co-acting cross bar l, while a similar ,conductor m extends upwardly from= the positive plate I) through the cover plate-e outside 'of e case. To the bar Z is fused or otherwise connected the conductor n, while to the bar we is similarly connected the conductor 0, forming the main conductors for the lamp circuit.

- In using the lamp one or two individual lamps may be employed, preferably two, for the purpose of providing an emer ency lamp in case of deficiency or efect in t e other.-

The lamps a: and y are of a well known type having screwed contact bases w, which for the purpose of providing resilient mounting are carried by a band of rubber 35 within the lamp compartment 9 and depending from the lower portion of a supporting frame 36 of any suitable construction, mounted within the upper portion of said compartment. The frame 36 may be of a suitable design to provide for the mounting of the make-and-bre'ak contact mechanism,

in the diagram of Fig. 11.

The co-acting contact elements g andg are 3 connected by conductors r and r respectively with the other termmals of the lamps w and throu h.

The plug 38 is provi ed with a terminal conductor 39 by which, when two such plugs are inserted, one at each side and connected with a generator, the battery may be charged;

The plug, being within the covering top 11, is inaccessible except when the top is removed. The resilient mounting of the lamps by the stiff rubber bands 39 permits of ample range of movement within the case 9, due to vibration or jolts without impair- I ment of the efliciency of the equipment.

For the purpose 0 preventing unauthore 1zed opening of the lens holder, I have proit with amagnetically operative lock- 1ng device, consistmg. of a locking dogor ratchet tooth 44 mounted on the end of a rounded spring 45 secured within the shell extending outwardly through a registermg openn? 46 therem and. adapted to engage one 0' an annular series of ratchet abutm'ents 47.

means'the lamps are rendered inaccessible without use of the magnet inpossession of the mine boss or foreman.

The battery and itscase, within the battery chamber 4, are preferably surrounded with a packing of any suitable material 51, as granulated cork or the like, loosely placed, so as to permit of slight movement of the battery and ample cushioning against the The lamp, as a whole, thus provides against derangement due to shocks or jars to which it is ordinarilys'ubjected in the somewhat rough and careless handling which such lamps usually receive. The entire construction is .very' strong and serviceable,

small and compact and not liable to get out of order. It, is readily'takenlapart for inspection or repair 1 and will be found to be very useful for the objects intended.
